Definitions

  • This invention relates to a control device of a headlamp's high and low beam, particularly to one provided with drivers to drive two light shields to operate for controlling a light projecting range of an automobile headlamp, able to attain change-over of high and low beam of an automobile headlamp.
  • an automobile is provided with a change-over device for controlling a headlamp's high and low beam, which is carried out by turning a whole headlamp base to different angles.
  • a change-over device for controlling a headlamp's high and low beam, which is carried out by turning a whole headlamp base to different angles.
  • the conventional way of change-over of a headlamp's high and low beam by turning the angles of the lamp base is likely to cause damage to electric wires when the lamp base is turned around and produces friction.
  • the objective of this invention is to offer a control device of a headlamp's high and low beam, needless to turn the lamp base, and able to control a light projecting range of the headlamp and achieve effect of change-over of a headlamp's high and low beam.
  • the control device in the present invention includes a lamp base, two drivers and two light shields combined together.
  • the lamp base has its periphery formed with a projecting edge and its interior provided with an arc-shaped reflecting surface and a lamp.
  • the two drivers are oppositely installed at two outer sides of the lamp base and respectively disposed with a driving shaft.
  • the two light shields are respectively assembled on the two drivers, having their opposite outer sides respectively bored with a through hole for the driving shaft to be inserted therethrough.
  • the two light shields are positioned under the front side of the lamp base and have their opposite inner sides superposed on each other.
  • a preferred embodiment of a control device of a headlamp's high and low beam in the present invention includes a lamp base 1, two drivers 2, 2' and two light shields 3, 3' as main components combined together.
  • the lamp base 1 has its periphery formed with a projecting edge 10 provided thereon with two projecting bars 11 opposite to each other and its interior provided with an arcuate reflecting surface 12 and a lamp 13.
  • the two drivers 2, 2' are oppositely installed at the outer side of the lamp base 1 and respectively disposed with a driving shaft 20, 20' having an outer end oppositely provided with a tangent plane 21, 21' and a top end bored with a threaded hole 22, 22'.
  • the two light shields 3, 3' are respectively assembled on the two drivers 2, 2', respectively and oppositely having an outer side bored with a through hole 30, 30' having a same shape as the outer end of the driving shaft 20, 20'.
  • Two fastening elements 31, 31' are respectively inserted through the two through holes 30, 30' and threadably engaged with the threaded holes 22, 22' of the two drivers 2, 2'.
  • the two light shields 3, 3' are positioned under the front side of the lamp base 1, having their opposite inner sides superposed on each other.
  • the two drivers 2, 2' are respectively fixed at the opposite outer sides of the lamp base 1, having the driving shaft 20, 20' respectively protruding out of the opposite sides of the projecting edge 10 of the lamp base 1.
  • the two light shields 3, 3' are respectively assembled on the two drivers 2, 2', letting the two driving shafts 20, 20' respectively inserted through the through hole 30, 31' of the two light shields 3, 3'.
  • the two fastening elements 31, 31' are respectively inserted through the through holes 30, 30' of the two light shields 3, 3' and threadably secured in the threaded hole 22, 22' of the two drivers 2, 2' and then have the opposite inner sides of the two light shields 3, 3' superposed on each other.
  • the control device of a headlamp's high and low beam in the present invention is to have two drivers 2, 2' driving the two light shields 3, 3' to carry out relative operation for controlling a light projecting range of the headlamp.
